Patent number: 11067068Abstract: The present invention describes the improvements due to alternated actuation cycles to reduce the delivery errors related to the pumping chamber elasticity, the actuator relaxation or hysteresis. The method actuates a pumping device with an optimal driving voltage profile, wherein the pumping device comprises a pumping chamber including a pumping membrane and a voltage controlled actuator connected to said membrane; the movement of said membrane being defined by three positions, namely a rest, a bottom and a top position. The method includes the actuation of the membrane with a pumping pattern including at least two different cycles: Cycle A: rest-bottom-rest-top-rest Cycle B: rest-top-rest-bottom-rest. The invention also relates to a device to carry out the method.Type: GrantFiled: August 6, 2018Date of Patent: July 20, 2021Assignee: DEBIOTECH S.A.Inventor: Eric Chappel

Patent number: 11020572Abstract: The device presented is designed to cause, in a mode of operation referred to as “normal” mode, a fluid to flow along this fluid path successively through the first cavity, the filter, the second cavity then the flow restrictor. The device is also designed to cause, in a mode of operation referred to as “purge” mode, a fluid to flow along this same fluid path through the filter but in the opposite direction to the normal flow of the fluid (in the normal mode of operation). Thanks to the “purge” mode, the fluid will detach impurities that have become trapped on the filter in order to clean same.Type: GrantFiled: July 8, 2016Date of Patent: June 1, 2021Assignee: Debiotech S.A.Inventors: Eric Chappel, Dimitry Dumont-Fillon
